In these drawings A denotes a receptacle which, in the present embodiment, is shown as rectangular, the outer surface thereof being beveled at its upper edge as shown at B, the said beveled surface extending along the ends and one of the sides and along portions of the other side. The beveled portion is also extended from the right hand end of one side to a point approximately corresponding with the line C and the receptacle at the opposite end has an area approximately the same as the one, just mentioned, so that a light-proof joint is pos sible when the cover is applied to the receptacle, the said cover having its flange E fitting the outside of the receptacle preferabl slightly flared toward its lower cd e alt ou h any suitable provision may be made or rendering the joint between the body and the cover light-proof and waterp)roof. The cover D has an apertured boss for filling and emptying the receptacle and it may be closed by a stopper D The cover D in the present embodiment of the invention is formed with a chamber F of any appropriate configuration to produce a clearance for the reception of the spool G. The under surface may be recessed to form a shoulder H constituting a seat for the plate I, it being understood that the shoulder H is formed at the ends as well as at the sides of the housin or chamber. The late I has a bracket attached to it b astenings such as K, and said bracket has a pintle L on which one end of the spool may'be mounted and it also may have an aperture L to receive a pintle of a spool of another type and hence provision is made for the operation of these brackets in conjunction with spools of different makes. lhe bracket J may also be formed with a placed M which frictionally bears against for holding the plate in place removed or applied shoulder the cover while the cover is bein' to the receptacle or ot erwise manipulated. A uide-way N may also be attached to the plate I by fastenings such as P and the ide-way constitutes a support for the bracket (,2 and the preferred constructionby which the bracket is frictionally held at different positions of adjustment on the support is to have the said bracket provided with seat flanges R which are enga ed by the edges S of the guide-way N. his arrangement permits the bracket to slide on the support so that a pintle T carried by the bracket may be forced into an aperture of a spool or a pintle of a s 001 may be caused to enter the aperture llof the said bracket. In any event, the spool may be rotatably mounted on the bracket so that a film which it carries may be drawn from it in a manner to be presently explained.

Within the receptacle, notched bars or ribs V may be stationed and the notches of the bar on one side of the receptacle should aline with those of the bar or rib on the opposite side as it is t e pur ose of. the inventor to apply a partition V\ to the notches so that the bars or ribs will hold the partition, and by reason of the existence of a plurality of notches, the partition may be at a point near or remote fromthe end wall or walls or with .relation to the other partition W and while I have shown but one rib or bar X for holding the partition W, it will be understood that a bar or rib with a plurality of notches may be used and that It would simply be a duplication of those already shown and described. In a majority of instances during the use of a developing device made in accordance with this invention, it would perhaps be preferable to have the relation of one of the partitions fixed and to provide an adjustment of but one of them and that wouldbe true particularly when employed in connection with a spool support in which but one bracket was made adjustable for thereby the bracket whose position is fixed could operate in conjunctionwith that portion of the receptacle having the fixed partition and the adjustable partition could be moved relatively to the adjustable bracket so that the space between the partitions could be regulated according to the width of the film carried b a spool to which the brackets were adj uste The partition W has recesses or notches w on its upper edge near each of its ends for a purpose to be ,presentl explained and it also has a right an lar ange w on one end which projects rom oneside of the partition and a right angular flan w at the opposite end and projecting mm the opposite side of the said partition. The

partition W also has a guidin rib w spaced apart from the flange w an a guiding rib 'w spaced apart from the flange w. The spaces between the flanges and ribs constitute guide-ways for film'and it is the purpose of the inventor that the partition can be reversed as will presently ap ear for attaining an adjustment between t e partitions additional to that permitted. by the presence of the notched bars or ribs.

The partition W has a downwardly extending and-tapered recess 10 on one side and a similar recess w on the opposite side, the said recesses being intended to engage and hold a plate w which is movable longitudinally of the seat and is in such relation to the sides of the seat as to bind against the said edges when it is in proper position with relation to the plate.

he partition VV' has a downwardly tapered seat 'w which receivesa plate 10, the construction being such that the plate wedges in the seat.

The partition W is beveled laterally on the two sides to and w fora, purpose to be presently explained anda coil form film holder '11) is attached t'o,the plate. The film holder is preferably formed of ribs or beads which taper from their bases to to their outer edges 10 and the purpose of these tapered members is to permit a film to be engaged at its edges so that it'is supported without liability of the coated surface of the film coming in contact with the sup ort. In the treatment of film. it is desira le to support it sd that there is no liability of the coated surface of the film con tacting with the support and it is also preferable to have the spaces between the volntions of the film uninterrupted as the free passage of fluid is allowed when there are no abutments or obstructions with which the fluid can contact. The film holder extends transversely of the partition and hence there is a space between the film holder and the side of the partition where the'said partition is beveled and this space constitutes a clearance for the free passage of fluid as it is a 'tated either by tilting the receptacle or sha ing it, and it permits the escape of air from between the volutions of the film.

The plate to carries a film holder 11) and it is of the same construction as the film holder w and need not be further described.

The partition W has a recess w in its upper edge and this recess and the recesses in the upper edges of the partitions W are intended to receive a flange w" on the plate I, which flange constitutes a guide for directing film to the space between a flange and guide of the partition W and between a y w" and guide w of the partition W. The outer end of the film support of each partition preferably terminates under or approximately under the flange of the partition so that film traveling between the flange and guide will be directed to the spaces between the volutions of the coil, so that the said film will-be coiled in the holders as it travels into the receptacle.

Each partition has apertures such as w to permit fluid and air to flow through the partitions and the current of the traveling liquid is depended upon to'treat the film and at the same time to carry ofl the freed deposits of metal used in sensitizing emulsions.

The cover D has an outwardly extending hood (Z so that there is a clearance between the hood and the receptacle for the passage of protecting paper or other protecting flexiblc material d used on photographic films put up in spools, and the space between the extension and receptacle may be closed by the tapered wedge closure which produrcs a water-proof joint between the ex tension and the receptacle so that the liquid may not escape from the receptacle regardless of whether it is on its end or side. The wedge is tapered at its side and ends.

The partition W has a flange v at its end at the bottom and the said flange fits in the notches of the bars V and the notches are so spaced apart that the partitions can be stationed at different positions with relation to the partition W so that the film holders receive films of the usual widths now on the market or which are now commonly used, but instead of moving the partition from one notch to another, a certain limited adjustment ma be attained by reversing the partition W and this movement of the partition will change the distance between the two partitions a less degree as one side of the partition extends a greater distance beyond the flange than does the other side, and s6 if the partition were simply reversed, the benefit of this minute adjustment can be had.

In the modified construction illustrated, 10 denotes a receptacle the outer surface of which is beveled at its upper edge as shown at 11, the said beveled surface extending alongthe ends and one of the sides and along portions of the other side. In Fig. 16 the beveled portion extends from the right hand edge to a point approximately corresponding with the line 12 and the receptacle at the opposite end has an area approximately the same as the one shown in Fig. 16, so that a light and leak -proof (idiot is possible when the cover 13 is applie to the receptacle, the said cover having its flange 14 which fits on the outsideof the receptacle preferably slightly flared toward its lower edge, although any suitable provision may be made for rendering the joint between the cover and the body li ht-proof and water-tight, as in the form eretofore described.

One wall of the receptacle, that is to say, the wall having the interrupted beveled surfaces is preferably provided with a series of recesses 14' forming seats for a spur or lug 15 on a sliding member 16, the said sliding member embracin r the edge of the receptacle and being adapted to move so as to be temporarily held with relation to any one of the notches or recesses 14:. Two of these sliding members 16 are provided and they constitute carriers or supports for the film holders 17, each of which film holders is of coiled formation with the volutions of the coil in spaced relation to the adjacent coil so that there isa clearance between them for the reception of film which is drawn from the spool and forced into the spaces between the volutions of the coil. Each of the film holders has a guide 18 connected to one of the volutions of the coil and the guide extends upwardly into position to engage film and guide it to the holder.

The cover 13, in the present embodiment of the invention, is formed with a chamber 19 of any appropriate configuration to produce a clearance for the reception of a spool 20. The under surface of the cover may be recessed to form a shoulder 21 constituting a seat for the plate 22, it being understood that the shoulder 21 is formed at the ends as well as at the side of the housing or chamber as shown in Fi 17. The plate 22 has a bracket 23 attache to it by fastenings such as 24 and the said bracket 23 has a spindle 24 on which one end of a spool may be mounted and it also may have an aperture 25 to receive a pintle of a spool of another type, so that provision is made for the operation of these brackets in conjunction with spools of different makes. The spindle 24 is rotatable in the bracket so that it may turn a spool to unwind the film therefrom and this spindle has connection with a crank 24 at the outer end of the housing, which crank may be connected to the spindle in any appropriate way so that it may be turned from the exterior, for the purpose stated. The brackets 23 may also be formed with a shoulder 26 which frictionally bears against the cover for holding the plate in place while the cover is being removed or applied to the receptacle or otherwise manipulated, although the said plate may be readily re moved by a pull which Wlll overcome the friction between these parts.

A aide-way 27 may be also attached to the ate 22 by fastenings such as 28 and the ui eway constitutes a support for the racket 29 and the preferred construction by which the bracket is frictionally held at different positions of ad'ustments on the support is to have the sai guideway provided with seat flan es 30 which are engaged by the flanged efges 31 of the bracket. This arrangement permits the bracket to slide on whose position is they engage in the support so that a intle 32 carried by the bracket may be force into an a erture of a. spool or a pintle of a spool may e caused to enter the aperture 33 of the said bracket. In any event, the spool may be rotatably mounted on the bracket so that a film which it carries may be drawn from it in a manner to be presently explained.

Within the receptacle, notched bars or ribs 34 may be stationed and the notches of the bar on one side of the receptacle should aline with those of the bar or rib on the opposite side as it is the purpose of the inventor to apply partitions 35 to the notches so that the bars or ribs will hold the partitions, and by reason of the existence of a plurality of notches, the partitions ma be placed at points near or remote from tfie end wall or walls or with relation to each other and while I have shown but one rib or bar 36 for holding one of the partitions, it will be understood that a bar or rib with a plurality of notches may be used and that it would simply be a duplication of those already shown and described.

In a majority of instances during the use of a devoloping device made in accordance with this'invention, it would perhaps be referable to have the relation of one of the partitions fixed and to provide an ad'ustment of but one of them and that woul be true particularly when employed in connection with a s 001 support in which but one bracket was ma e adjustable for thereby the bracket fixed could operate in conjunction with that portion of the receptacle having the fixed partition and the adjustable partition could be moved relatively to the adjustable bracket so that the space between the partitions could be regulated according to the width of the film carried by a spool to which the brackets were adjusted.

The partitions which I have selected to illustrate as modifications, comprise plates 37 and each of them may have an aperture 38 through which liquid will fiow from the ends of the receptacle to the space between the partitions and, furthermore, the edges of the plate may have recesses 39, 40 and 41 which produce clearances between the edges of the plate or partition and the inner wa of the receptacle for the purpose of permitting the circulation of the fluid and the side edges of the said late at the lower ends may be further provi ed with notches 42 and 43 to reduce the width of these plates where the notches of the bars or ribs.

The surfaces of the plates 37-which face each other, are preferably beveled from the center to the ed es to increase the clearance between the 'su aces of the plates and the ends or edges of the film and this allows the metallic deposits from the film to gravitate .from the film and escape during the developing operation or while the film is being treated.

The cover 13 has an apertured boss 44 to which a stopper 45 is applied, and the said cover has a rearward extension 46 which clears the wall of the receptacle and forms a. space between the cover and receptacle through which paper 47 is drawn, as the film 48 is unwound from the spool, it being understood that when it is desired to transfer film from a spool and the film holders in the receptacle, the film and protecting paper which is wound on the spools of films now in ordinary use is partially unwound until the point is reached where the film appears. The plate 22 carrying the spool supports is then applied to the cover with the spool supported 1n the housing of the cover and with the advancing edge of the film below the plate 22 and outside of the housing. The guides 18 preferably extend above the flange 49 of the plate 22 and hence the film is practically confined between the guide and the carriers of the film supports and as the film is unwound, it is forced into the film support with the volutions of the coiled film in spaced relation to one another so that there will be no abrasion or injury to the coated surface of the film and by reason of the spaced relations of the volutions, fiuid may freely circulate from end to end an gain access to the whole surface of the film.

After the film and protecting paper has been wholly unwound from the spool, the projecting portion of the protect ng paper is removed as far back as it is possible to cut or tear it under the projecting port1o ns o the cover. Thereafter, a closure 50 s inthe flange of the extension 46 and the side of the receptacle, making the joint light-proof and water-t1ght, so that the receptacle can be moved to agitate the fluid therein for the purpose an ob ects 1ndicated.

The closure 50 has a recess 51 forming a clearance for the protecting paper and for the rojecting portions of the supports for the lm holder, and the closure 50 is tapered toward its upper edge so that it will have a wedge action between the flange of the rearward extending portion of the cover and the surface of the side of the receptacle.

The term film which has been employed in this specification is used in a generic sense and is intended to include any base appropriate for carrying a sensitive emulsion or coating such as is employed in photography or arts where light affects the coating is subjected to the action of ii and comprehends not only the so-called coated celluloid or paper films, but also photographic printing papers or films as it has been found that printing pa ers used in dphotography can be develope washed an fixe with the same facility as the now commonly used celluloid film can be treated.

When the cover is applied to the receptacle, the flanges of the plate 22 are supported on the upper edges of the partitions, butthe plate is held on or in the cover when it is removed by the friction heretofore de scribed.

In the modified embodiment of the inven tion, the sliding members 16 have loops 16 by which the film holding members are con nected to the sliding members.

\Vhen operating the device, the film is of course delivered to the holders in the man ner heretofore described and initiatively, the receptacle preferably is supplied with developing solution or fluid, and after the device has been manipulated to develop the film, the stopper 45 may be removed and the developing fluid may be poured outof the receptacle. Thereafter, water may be de livered to the receptacle and the film may be washed, rinsed and then the fixing fluid or solution can be placed in the receptacle and the film can be subjected to the action of the fixing fiuid, and that may be poured ofi and the water may again be placed in the receptacle for finally washing the film and tlllS can all be accomplished without exposing the film to the light, or the sequence of treat ment may be varied to suit the requirements in practice.
